Quoted from Nickbtx:
I'm not trying to cause a stink, I'm more curious if any of them have stickers (I'm speaking specifically about the dome). At a glance the blue areas look like a sticker, but I still believe that they are paint. I had an early concern that a vinyl decal might lift, particularly when on a domed surface. I may be all wrong, but why would there be blue paint bleeding out from under a sticker? I may try to get pictures later.
The cylindrical part of the droid does look like a vinyl sticker but there are no issues with it. Looks great. I doubt the movie prop looked any better.
Some people posted some pics earlier that looked like stickers (e.g. post #840, #764). I'm not sure if these were some kind of prototypes or early production versions as mine also appears to be painted also. In one image the rectangle that represents logic display seemed crooked although it looks fine on mine, and this is on the back of the droid so not as many pictures of that part have been posted.
Strangely in the version that was first seen on the Stern tour before it was announced, as well as some early pictures the holo projector on the front seems to have been replaced with just a screw. The misassembled version also seems to be shown on some distributor websites which is unfortunate. The dome attaches to the underlying metal structure at three points including at the holo projector that acts as a nut.
